Definitely the reissue & classic flap! The reissue because it's the "original" Chanel bag. The classic flap because the CC lock is recognizable & iconic. If you have these 2 bags in any color/size/leather/hardware combination, then you're all set for your Chanel collection. Timeless, classic, & versatile. To me, these are the equivalent of the birkin & kelly from Hermes.
